( 1 )  Staircases General access and utility

Staircase design is covered by BS5395: Part 1, BS5395: Part 3 and BS5950: Part 5. Generar boal guidance on staircase design is contained within the new Approved Document Part K – 2013 (Section K1 – Stairs, Ladders and Ramps) of Building Regulations. This approved document supersedes previous guidance in Approved Documents Part M and Part K relating to staircases and guard railing.

The Building Regulations have recently been amended to remove conflicting guidance across different documents. In particular, guidance for staircase design (previously covered by “Parts K & M”) has been combined into a single document: “Part K” – which became effective from 6th April 2013.

All our staircases are designed to meet the requirements of “Part K”, for use within industrial premises. Staircases for use within other types of premises (such as, commercial, retail, institutional, general public access etc.), may need to meet additional requirements, and can be quoted separately.

Staircase construction

Staircases are either manufactured and constructed from rectangular hollow section or flat plate steel with the handrail vertical posts ( 1500mm nominal centers ) welded to them and the top rail ( handrail section ) generally 50mm x 50mm x 2mm box section fully welded to them. A mid rail ( knee rail ) is welded mid way between the stringer and the handrail. Stair treads are either plain steel plate or durbar plate ( for industrial applications ) are generally bolted into the stringers from welded plates within the stair treads. The stair stringers are bolted to the ground floor ( and mezzanine ) from angle plates welded to the stringers. The goings for a general access staircase are 250mm and the risers are 170mm maximum. For a utility staircase the risers are 190mm and the goings are 250mm. for public access staircases the handrail sections are extended by 300mm at the bottom and top of the staircase.

( 2 )  Staircase Mid – Landings

Staircase mid-landings split the height of the staircase when the levels of the mezzanine exceeds the allowable number of risers for an industrial general access or utility staircase. they are mandatory for a public access staircase.There are three types of mid landing as follows.mezzanine floor.

Mid  landings are manufactured from 50 x 50 x 3mm RHS and are fully welded with cross bases for lateral stability.the top plate is either 4mm plain steel or durbar plate. Top landings are either 1000mm x 1000mm for utility staircases or 1200mm x1200mm for general access design. Mid  landings can be made in two sections in the height and bolted together on site for ease of handling. They can also be supplied in kit form and are fully bolted on site, again for ease of access to the site and easier builds. Handrails ( edge protection ) for straight flight staircase on the mid – landing have four rails ( loose ) which are tec screw fixed into the top and bottom handrail posts of the staircases. Handrails for 90 and 180 degree platforms are made as a complete section from 50 x 50 x 2mm RHS with 30 x 30 x 2mm Knee rails and are bolted to the top plate section. This also is applicable to the top landing construction.

There are three types of mid landing as follows.mezzanine floor.

  1. Straight flight single width for in line staircases
  2. 90 degree single width -
  3. 180 degree double mid landing

( 3 )  Staircase Top – Landings

Staircase Top landings are used at the sides or front / rear of the mezzanine floor platform. There are two types of mezzanine floor top landings. Top landings are manufactured from 50 x 50 x 3mm RHS and are fully welded with cross bases for lateral stability.the top plate is either 4mm plain steel or durbar plate. Top landings are either 1000mm x 1000mm for utility staircases or 1200mm x1200mm for general access design. Top landings can be made in two sections in the height and bolted togeather on site for ease of handling. They can also be supplied in kit form and are fully bolted on site, again for ease of access to the site and easier builds.  Handrails for 90 and 180 degree platforms are made as a complete section from 50 x 50 x 2mm RHS with 30 x 30 x 2mm Knee rails and are bolted to the top plate section.

  1. Straight flight single width for in line staircases
  2. 90 degree single width

 ( 4 )  Pallet Gates

Pallet gates are designed to provide a safe barrier at a pallet loading area of the mezzanine floor. Pallet gates can either be mounted on the front face of the mezzanine floor or can also be within the mezzanine floors it self. The pallet gate can be of a simple sliding section ( usually tubular ) which slides within the handrail sections, or more complex stand alone units for wider, deeper and higher loads, Whatever type is implemented, it always forms an integral part of the edge protection ( hand-railing ) or balustrade. Up and over pallet gates are the most common and cater for pallets and loads 1500mm wide x 1200mm deep x 1800mm high. The up and over pallet gate which we manufacture is lightweight and easily operated running in phosphor bronze bushes.
